Looking at trading combines before fall. Have found two low hr. machine with my local dealers. I have ran 2388 ih. and don,t know a lot about the JD. What are some of the good & bad points on both of them. Both dealer are good to work with, so that part realy wouldn,t matter. Looking at maybe going to a 35 ft. draper head and a 12 row corn head next year. Thanks for any information.
